1/2" Press Bronze Spring Check Valve

The Viega 79035 is a low-lead bronze check valve designed for 1/2 inch press connections in potable water systems. It uses an inline spring mechanism to prevent backflow and is rated for horizontal or vertical mounting.

Build integration and clearances

The press-by-press ends join directly to compatible tubing without solder or threading, reducing installation time and eliminating open-flame requirements. A cracking pressure of .5 psi allows flow to begin with minimal head loss, while the EPDM seal handles temperatures up to 200 degrees F at 200 psi.

Ideal for and not for

This valve suits contractors and facility managers installing press-fit copper systems where lead-free bronze and a stainless steel spring are specified. It is not for steam lines, applications requiring a full-port design, or systems that exceed the 200 psi water pressure limit at elevated temperature.
